There was once an iOS app called "Baking with Dorie" that had a similar presentation. It caught my attention because I was interested in novel ways to represent recipes. It's no longer in the app store, but there are a few reviews out there with screenshots, e.g.

It seems to me that if you added time to one of these wiring diagrams (for the recipe use case), you would have a Gantt chart. This might also be leveraged to plan parallel processes in a recipe (e.g. making the second part of a mole sauce while waiting for the chilis to soak).

For complex recipes or meals, I could also see using the wiring diagram to represent a high level flow between sub-recipes, and then drilling down into a node to view the diagram for that sub-recipe. You might be able to mock this up with "milanote".

In the past I've built a dependency diagram for a complex dinner (dishes from the Eleven Madison Park cookbook) by scanning my markdown transcription of the recipes and generating a 'dot' file for graphviz. For planning meals like this, I think a Gantt-like representation would be useful. Some components were made a day or two ahead, some same day, and some steps had to be executed at the last minute.
